BTW, have you replaced the original rubber brake hoses? Originality is one thing but those original hoses do not last. The may look OK but after 38 years they won't hold the pressure during a panic stop.

I know from experience: I had a front brake hose blow out on a Z11 I had back in 1980, and those hoses were only 11 years old at the time. Forget about the theory that dual master cylinders will divert the fluid to the rear system. Dont bet your life on it! It was quite an adventure: no brakes trying to stop the car as it went down a hill, picking up speed to about 100 mph, on a tree lined road, threading the needle through a four-way intersection with a red light, past a school as the buses were pulling out. I was only able to stop as the car crested the next hill, with the emergency brake jammed all the way to the floor. I was 17 at the time and I have never ignored my brake lines again.

Oh, and listen to your mom about always wearing clean underwear. I definitely needed a new pair after that...and a new seat cover as well.
